Zoroaster

c. 600 BCE — Persia, Ancient Iran

Today: Northeastern Iran / Central Asia

An Iranian priest taught that the universe is a battleground between a good creator and a destructive force, that history moves toward a final judgment, and that each person's choices count toward the outcome. Where older religions had capricious gods to be appeased, this one had a moral structure with a direction. Under Persian kings it became a state religion, and its ideas — heaven and hell, a coming savior, angels and demons, a final reckoning — spread through the Jewish exiles in Persia and, from there, into Christianity and Islam.

Worth knowing: Perhaps 100,000 Zoroastrians remain, mostly in India and Iran. The ideas are everywhere: several billion people hold beliefs about judgment, an end of days, and cosmic good against evil that trace to an obscure Iranian priest almost nobody can name.

Pattern: Ideological movement — A belief system rises, spreads, institutionalizes, and then schisms — changing the rules people accept as legitimate.
